Abstract
The invention relates to a seal structure for scaling the inlet/exit gate passageway of an elongated object (1) from a process cavity (A, B) or into such a cavity. The seal structure comprises sheet-metal structures, which essentially delineate the passageway and are removably mounted on the frame structure (3) of said process cavity, and a sweeping seal element (13) enclosing the passageway. The sheet-metal element structures comprise at least two sheet-metal elements (14, 15, 15x) that have a shape taperingly departing from the frame structure (3) of the process cavity so as to be inclined in the nominal travel direction of the object (1) are kept compressed mutually against each other so as to hold a seal element (13, 13x) therebetween.

A seal structure for sealing the inlet/exit gate passageway of an elongated object (1) exiting a process cavity (A, B) or entering such a cavity, the seal structure comprising sheet-metal structures, which essentially delineate said passageway and are removably mounted on the frame structure (3) of said process cavity, and a sweeping seal element (13) held in place by said sheet-metal structures and enclosing said passageway so as to provide a seal against the outer surface of the object traveling through the passageway, characterized in that said sheet-metal structures comprise at least two sheet-metal elements (14, 15, 15x) that have a shape taperingly departing from the frame structure (3) of said process cavity so as to be inclined in the nominal travel direction of the object (1) and are kept compressed mutually against each other so as to clamp a seal element (13, 13x) therebetween.
